It will be understood, however, that the particulartype'or' style of printing press is immaterial and that my invention, as'hereinbefore st'ated,- 1nay be built as an integral part of theprinting press structure or as'anvattachwent, but for the purposes of anunder stmiding of my invention I will proceed to" describe the same asherein illustrated and as these-me is-used in practice, that is as anattachment to :1 Gordon press modified slightly in the" manner stated Myattachment is provided witha nain frame't forming a support for thedifferent working'parts of the attachment and secured in any suitablemanner to the printing press frame 1. At the upper end of this-frame 4'I mount an endless conveyor comprising a pair of transverse rollers 5and 6 and 1 suitable endless belt 7. By preference this belt is madecontinuous from side' to side and as clearly shown in Fig. the sameslides upon the upper surface of a support 8 located between saidrollers alongthe toprea'eh of the belt. This belt is adapted to receiveand to slowly feed as required the pile of paper which is placedthereupon in combed-form and kept in that condition and fedby such belt.For the purpose of properly feeding the paper, the endless belt is movedas required, and in suitable manner,

for'instance; by means of the-ratchet wheel 9 operntivelyconnected withthe front roller and cooperating with the pawl 10 which is mounted uponthe pawl carrier 11 whose oscillation and proper timing as to" movementwill be hereinafter describedl The front edge of the pa-p'er is stop)'ed"l)y means of n cross bar 12 having a seriesofrearwardly-e-Xtend-ing fingers 13 which are formed separately orintegral therewith and adapted to liei'in grooves 1 formed "in the beltby'reason ofthe fact that the front roller Gisitself provided with :1series of elm-umfere'n tial grooves 6 ns'clearlyshown in Fig. 5. It willbeunderstood that owing to the tension and pliable nature of the belt.the latter will assume the some surfer-e" characteras the frontroller(i.- lly this means the paper will beproperly received and stopped bythe fingers l3 and be prevented from following the belt.

For the purpose of separating the top sheets one at a time from the pileof sheets a transverse roller 14, preferably corrugated and of suitablematerial, such as rubber, is provided. This roller is arranged to be oscillated in contact with the top sheet of paper first in one directionand then in the other and to be slightly raised during the time thatsuch sheet is being pulled from the pile by the feed rolls hereinafterdescribed. In one of said oscillations this roller 14 causes the paperto buckle and because of this function I will hereinafter refer to thesame as the buckling roller. This roller is journaled at its ends inbearings 15 and provided with the central shaft or axis 16. In practicethis shaft is connected at one end with a bevel gear 17 adapted to meshwith a corresponding bevel gear 18 (Figs. 2 and 6) mounted on and drivenby the vertical shaft 19 carrying at its lower end a similar bevel gear20. This latter gear is I adapted to mesh with another bevel gear 21 Iroller is to cause the to which isoperative'ly connected an oscillatingcrank arm 22 driven by means of op erating connections hereinafterdescribed. In .order to prbvide for a slightvertical movement of thebuckling roller a sliding connmtion is provided between the shaft 19 andeither one of its bevel gears in the present instance bevel gear 18.

The buckling roller cooperates in the huekling operation with a normallyfixed but adjustable transverse bar 23, extending across the pile ofsheets and in proximity to the top sheet thereof. The object of thisaper to buckle or move upwardly when the buckling roller is oscil latedin a direction to move'the top sheet rearwardly as to its-front portion.In order to accommodate sheets of different thickness this roller 23 isadapted to be adjusted toward or awa from the buckling roller. Tothisend an as a means for supporting such roller, the latter isrotatably mounted on a shaft 24 which is adjustably secured inlongitudinal slots 25 formed in blocks 26 at each side of the machine,all as clearly indi bated in Figs.'5 and 6. These blocks are carried byandextend forwardly from 'a cross frame comprising the cross bar; 27,preferably having on its underside a sup plemental bar or piece 28 ofsuitable material, such as wood, adapted to press direct-ly upon thepile of sheets. Said frame also comprises upright ortions 29 located atthe ends thereof an connectedby the cross shaft 30. This shaft extendsthrough and is guided by substantially vertical slots 31 in an upwardextension of the attachment frame 4 and the same, together with theentire cross frame, is held downwardly upon the paperwith a yield ingpressure b means of springs 32 arranged. in said slots 31. These springsmay be adjustable in tension in any suitable i'nanner as by means of theadjusting screws 33. Tu the present instance the roller 23 is held inadjusted position by the bearing shaft 24 adjustable in the slots 25 andheld in adjustedposition by means of the clamping bolts St, the ends ofthe blocks 26 being properly slitted as clearly shown in Fig. 5 toprovide for such clamping.

The cross bar 28 and the roller 23 are adapted to press upon the pile ofsheets with a yielding pressure but arranged to be slightly withdrawntherefrom at the time when the top sheet after being buckled is beingfed forwardly into'the machine by the feed rolls in the mannerhereinafter explaincd. To this end I provide a pair of oscillatinglevers 35 arranged at opposite sides of the machine as indicated inFigs. 5 and 6 with their rearward ends in contact with the underside ofthe vertically movable boxes or blocks 36 which slide in the slots 31with the result that when said levers 35 are oscillated upwardly thecross bar 28 and roller-'23 will be slightly raised against the tensionof the springs 32. T0 afford proper movement to said levers, the latterare secured to the cross shaft 37, one of said levers, as shown in Figs.4, 5 and 6, being connected by means of the link 38 to an oscillatingbell crank 89 pivoted on the main frame 4. This bell-crank has a camroller 39 which is so arranged as to cooperate with a cam 39 secured tothe cross shaft 48, thereby giving the roller 14 a positive movement toand from the paper.

In front of the buckling roller is arranged a series ofrearwardlyeatending fingers 40 whose rearward ends extend downwardly incontact with the top sheet of paper and whose forward ends are. securedto or form a part of a transverse rod or shaft 41 having an oscillatingmovement. During the time when the buckling roller is moving in itsclockwise direction (Fig. 5) for the purpose of moving the front end ofthe top sheet of paper rcarwardly and buckling the same, the fingers 40are slightly raised to remove any interference with said operation butafter the front edge of said top sheet of paper so being acted upon haspassed to the rear of these fingers, the latter are moved downwardlyupon the second sheet of paper which will subsequently become theuppermost one, with the resultthat in the movement of the bucklingroller in the opposite direction, the front edge of the top sheet willbe directed and deflected by said fingers in an upward direction andfree from the pile of paper. These fingers 40 are oscillated in propertime with the other mechaend of a lever 44. i This lever, which ispivoted at 45, is provided at its Eenter with a cam roller 46 adapted tocotiperate with and be actuated by a=cam 47, secured to bne of the, maindriving'shafts 48 of the machine. In order-to autom'aticaliy keep auniform depth of paper underneath the buckling roller, that is a uniformthickness of paper between the lower' surface of such roller and theupper surface of the feed 'belt 7, I provide suitable means which, inthe present instance, consists of nechanism controlled by the relativeposition of. the buckling roller' for actuating the feed belt. As

shown, a vertical link 49 is connected at its upper end'with bell crank39, Figs. 4 and 15, while its lower end is pivoted to the lever 50, theextreme end of -which is connected by means of a link 51 to the outerend the buckling roller is lowered from its normal position, the link 49is forced slightly downwardly, by reason. of its connections {gs Withthe bell crank 39 and link 38, with the result that .the lever 50 isslightly oscillated in a clockwise direction, (Fig. 4) so that, a camroller 52 is brought into the path of travel of the cam 58 secured tothe driving shaft 48. When, in its rotation, this cam contacts the'camroller 52, the pawl-carrier .11 is moved upward by reason of itsconnection with the lever 50 through the link 51 and the pawl 10 will becaused to en 5 gage a tooth or teeth as the case may be on the ratchet 9and move the feed belt for- .wardly in slight degree but sufficient tomove the pile. of paper forwardly to provide the uniform depth. of paperunderneath the bucklingroller.

Vihen the top-most sheet of paper is fed forwardly by the bucklingroller and tie flected upwardlyhy the fingers 40, the same will bedirected between the two feed rolls 54 and 55, of which the former ispositively driven as hereinafter explained, and of which the latter isan idler, b and 6. From these feed rolls the sheet of paper passesbetween a second pair of feed rolls 56 56 and 57, the former being apositively driven roll and the latter an idler. This idler isspring-pressed toward the feed rolls 56 by means of a spring 58, whosetension may be regulated by the adjusting screw 5%).

The paper is uided to the first set of feed rolls by fingers 40 and intothe second set of feed rolls by means oi'guides 60. Figs. 4 an,d 5. Fromthe latter set of feed. rolls the paper passes downwardly in an inclined60 direction between the carrying tapes 61, the

paper being presented to a transfer frame and presented thereby to theprinting mechanism and subsequently delivered from the machine.

I will now proceed to describe the means whereby the machine isautomatically stopped whenever the feed of paper is for any reasoninterrupted or if the paper should be stopped or clogged in its feedingor improperly fed. Speaking generally, such stop mechanism consists of acontrol; ling means placed in the path of the sheets of paper betweenthe feed tapes for controlling ,the stop mechanism proper which, in thepresent instance, operates an electric switch controlling the power ofthe machine and also operates a brake which here acts uponthe fiy-wheelof the press.

Describing the present embodiment of my stop mechanism as herein shown,(Fig. 7), I secure upon a transverse stationary shaft (32 a double lever63 which is connected with a bell-crank gear 64 by means of link 63*.

I This bell-crank gear 64 is secured to a trans- 20 of i; the pawlcarrier 11 hereinbefore' described. -When in the feeding of the paperverse rock shaft 65 and meshes with the gear portion of a segmental gear66 which is secured to a rock shaft (57. These gears and pinion arelocated adjacent among the feed tapes, near the lower end thereof, thegears being. arranged at one side of such tapes. The double lever 63 isprovided with a camroller 68 which coiiperates with the cam wheel (39 ashereinafter explained. Upon the rock shaft 67 is loosely mounted a bellcrank 70 which has a yielding driving connection with such shaftby meansof the spring 71 and the arm 72, the spring being connected by studs73*with said arm and bell crank respectively. Such construction thusprovides for a yielding lost motion. The forward end of the bell-crank70 is hollow or bifurcated '(Fig. 3) and there provided with a detent 74of irregular shape and pivoted at its central portion at 75. This detentis bell-crank shaped as to its main portion, but provided at one endwith a hook 76, the other end being properly weighted, as by means ofthe slotted arm 77 to keep the same in a normal position. The limits ofmovement of this detent are defined by'means of the stop pin 78 receivedby the slot in said arm. This arm is of such a length as to present thedetentto the paper being fed through the machine and to cause it tocontact such paper and to be oscillated thereby independently -of thebell-crank 70, in the manner hereinafter described. This detent adaptedto coiiperate with a disk 79 loosely mounted upon the rock-shaft 65 andof the peculiar shape illustrated in detail in Fig. .13. This disk isprovided upon one side with a hook portion 80 and also with asubstantially righhanglcd notch 81, while the other side of such cam iscut away or reduced at 82 for a. purpose hereinafter made apparent. Suchdisk is kept in a normal position relative to its shaft or axis with ayielding pressure, as by means of a. sprin-g. 83 secured at one end to apin 84, and at its other end to a pin which is mounted on a fixedbracket 86. Upon the rock shaft 65 is mounted a second disk 87 which Iwill herein refer to as the positive or ratchet disk. This disk, whichis illustrated in detail in Fig. 14, is loosely mounted upon this rockshaft or axis 65 and adapted to cooperate with the spring-pressed pawl88 pivoted upon a pawl-carrier 89 thatis secured in suitable manner tosaid rock shaft 65, detail of which pawl and pawl carrier are shown inFigs. 10 and 1'2. This pawl 88 is adapted to engage the notch 90 in theratchet disk 87when. permitted to do so by the disk 79, as hereinafterexplained, and to this end this pawl 88 is of sufiicient width tocooperate with both disks 79 and-87 as indicated in Fig. 12. Thetendency of this pawl is to engage said notch 90 but it is preventedfrom doing so whenever the paper is being fed and also being fed in proer manner by means of the other disk 79 w ichacts as an interference tothe action of said pawl and therefore controls the same,for which reasonI will refer to the disk 7'9 as the controlling disk. i f

Referring to the operation of the mechanism as thus far described, andassuming first that the paper is being fed properly to the machine, theparts are so timed that when the gears 4 and 66 are actuated in themanner described a sheet of paper is then being fed along the feed tapesin proximity to the bell crank 70 and its detcnt 74. During the feedingof this sheet the segmental gear 66 is moved in clockwise direction,that is in the direction of the arrow in Fig. 8 and the bell crank 70 ismoved in-the same direction. During this movement the free end of thehook 76 will come into contact with the sheet of paper and the detent,being very light in weight, will be rocked by the paper during thecontinued movement of the bell crank 70 as shown in Fi 8, with theresult that such detent will ti: retracted as to its hook end and willmove upwardly to a plane above or coincident with the notch 81 of thecontrolling disk 79. Just as soon as the top edge of the sheet of paperhas passed by said plane, the hook end of the detent will drop into saidnotch 81 and take its position therein as indicated in Fig. 9.Thereupon, during the reverse of the oscillation of the bell crank 70such detent will move the controlling disk in a clockwise directionagainst the tension of its spring 83. During the first describedmovement of the segmental gear 66 the rock shaft (55 being oscillated inan anti-clockwise direction (Fig. 8) the pawl carrier 89 and its pawl 88are oscillated correspondingly, at which time the pawl will ride uponthe peripheries of both disks. In the reverse oscillation of the paptshercinhcfore referred to the pawl carrier and its pawl will move In aclockwise direction and the controlling disk 79 will be moved in unisonby the detent in the manner already explained, with the result that thepawl 88 will be disabled or rendered inoperative as shown in Fig. 9inother words such pawl will be prevented from engaging in the notch 90 ofthe ratchet disk and the latter will therefore not be operated. Theparts of the stop tnechanism now being described are the controllingelements and the parts hereinafter described will not bedisturbed intheir said position.

Now assuming that for some reason the feeding of the paper has beeninterrupted and no paper is running or being fed by the feed tapes, thedetent 74 will not be moved outwardly on the upward movement of the bellcrank 70, as hereinbefore described, inasnnleh as no paper is nowrunning, with the result that the hook end 76 of the detentwill engagethe hook S0 of the controlling disk which, in the present instance, isheld by spring 83 against adjustable screw 91, and the arm 72 continuesto oscillate by virtue of the yielding driv ing connection 71. In thesucceeding movements, the controlling disk 79 will not be oscillated bythe detent but will be held in no mal position by the spring 83 so thatin the return movement of the rock shaft 65 the pawl 88 will not beinterfered with by the controlling disk but at the proper time will dropinto the notch 90 and in its continued movement will slightly oscillatethe ratchet disk 87. As a result, the link 92 which is pivotallyconnected to such ratchet disk will he moved in the direction of itsarrow shown in Fig. 11. This link 92 is pivotally connected at its lowerend to a bell crank pawl 93, which acts as a trigger holding a lever 94and its associated parts in the. position indicated in Fig. 7.v Thislever and its associated parts are mounted to oscillate on the shaft 62as an axis and the same is provided at one end with a depending lug 95which directly cooperates with the trigger 93. This lever 94 is suitablysecured to a rock shaft 96 whose upper end is provided with a lateralextension 97 carrying at its free end a stud 98 and a cam roller 99,said stud and roller'being on axes at right angles to each other, Fig.15. The cam .roller 99 is located on one side ofthe stud 98, in positionto cooperate with the eriphcry of thecam 100, while the stu 98 islocated on the under side of extension 97 in position to cooperatewithiia projecting portion 101 of said cam, Figs. 7 and 15. Vthen thetrigger is operated in the manner explained the resistance againstthemove ment of the bearing frame 102 in a clock-v wise direction (Fig. .7)is removed, and the same will be caused to move in such direction assoon as the cavity 103 in the earn wheel is presented to the cam roller99.

the bottom edge of same will be gripped the cam 15st for producing thedesired move cross strip 155 constitutes one of the grip ping aws forengaging the bottom edge of the paper, the second jaw consisting of astrip 158 pivoted upon said cross strip and 2 having projections 15$)forming the jaws proper adapted to cooperate with similar projections orjaw members 160 on the cross strip. The pivoted cross strip is heldpressed with. a yielding pressure against the other strip by meansofsprings it'll with the result that the gripping jaws are closed undernormal conditions. The lower members of the jaws are provided with aseries of pins 162 acting as registering pins for the paper so that theand held by the transfer device in proper registered position.

For deflecting the paper from the plane of its travel to the printingmechanism in order that it. may be delivered at an angle to the deliveryinecl'iai'iisni, I employ substantially the same deflect n fingers asshown in my prior application, but I so arrange and adapt the same thatsuch fingers are given an additional function, to-wit the stripping ofthe paper from the platen. As shown more particularly in Figs. 1, 3 andl, the series of fingers which. are here three in number comprise twoportions, :1 main portion 103 and a longitudinal portion 164-, which isadjustable in the base portion for shortening or lengthening the fingersquired. in practice the base portions 163 .are provided withlongitudinal channels to receive the portions 164 which are 111 the formof thin strips, the same being clamped in proper adjusted position bymeans of the clamping screws 165. The fingers are secured to a hollowcross shaft.- 166 which is loosely mounted on shaft 166 and at Whoseends are secured the hell cranks 1(31' held spriug- )rcssed by means ofthe springs 168. The tinge-rs, as well' as the shaft 166, are providodwith a parallel ruler motion by reason of the provision of the twosimilar arms H39 and lit) and the connecting link 171 the arms H39being; pivotally connected at their lower end with the cross shaftltitiand at their upper ends to the fixed point: 172. The upper arm W0 issecured to the cross shaft l7?) which is provided with a crank arm 1.74connected by means of the linlt'175 l which is pivotally connected tothe operatmg lever 176. For the purpose of imparting j the necessaryrocking movement to such latter lever, the same is provided with a cam jroller 17? adapted to cotipe ate with the cam j wheel 178. By means ofthis operating connection deflecting fingers are given the del siredmovement toward and away from the j platen, the innermost position ofsuch 3 lingers being illustrated by the dotted lines l in Fig. 4. Toobtain the additional or l clamping function I provide a spring lpressed plunger 179 which is adapted to be projected at the propermoment against one of the arms of the bell crank 16?, with the resultthat the fingers will be moved farther to the left (Fig. 4:) and againstthe paper, 1' thereby clamping the same against. the platen to strip thepaper from the type bed or form. in the present instance these plungcrs1.7.) are actuated by means oflho bell cranks 180 having pin and slotengagement therewith and provided with cam rollers-1S1 cooperating withthe cam wheel 182. The desired adjustment of the clamping action isobtained by means of the adjusting screws 183 as well as the adjustableabutment 184.. The movement of the plungers i s outwardly against thetension of the springs 185 which restore the same to normal position.IAs the transfer frame moves upwardly and is in proximity to saiddefiectii lingers, the latter move outwardly, to the position shown infull lines in Fig. 4 and such frame continues the position to receiveand grip the bottom edge of the sheet. of paper. In this upward movementof the transfer frame, the jaws thereof are opened by contact with thecam plates i813 and with. the rollers 18? mounted upon the movablemembers of the jaws. After the transfer frame has moved below the rangeof the dedotted line position indicated in Fig. 4 and the plungers 179thereupon rock such fingers inwardly as to their lower ends and therebyclamp the paper against the platen to strip I it at the proper time.After the paper has thus been stripped from the form, the de fleetingfingers are released from their clamping or stripping position and uponthe continued upward movement of the transfer frame such fingers aremoved outwardly to a position of non-interference, as already explained.In the forward movement of the transfer frame the top edge of the paperis deflected laterally to the left (Fig. 4-) to the delivery mechanismby means of the inclincd projecting portions 188. The deliv crymechanism comprises in the present instance endless belts or tapes 18%)and 190 and suitable pairs of rollers 19.1 and 192.

The transfer frame is operated in the present instance from the crossshaft through a series of operating conncrtimis fleeting fingers thelatter is moved to the now to be described. To said shaft 48 is secured.a crank arm 193 to which a link 194 is pivotally and adjustablyconnected. The upper end of the link is slotted and provided thereinwith a sliding bearing box 195 held in its upper position by means ofthe spring 196. The upward limit of movement of the box is adjustable bymeans of the adjusting screw 197. This bearing box is pivotallyconnected to a vertically movable rack guide 198 sliding on a guide bar199 and meshing with a pinion 200 which in turn meshes with and drives apinion 201 secured to a trans verse shaft 202. To this shaft near itsends are secured two pinions 203 which are adapted to engage the rackbar portions 204 of the transfer frame. The degree of movement of thetransfer frame is adjustable to a n'icety by means of the stops 205which are adjustable up and down upon the rack bars 204. The slidingbearing box 195 in connection with the spring 196 forms a yieldingdriving connection for following up or compensating for the movementofthe operating connections after the stops 205 have come in contact withand have been arrested by a fixed part of the machine frame, in thepresent instance the bearings 157 of the rack bars.

lVhen my invention is made as an attachment to the usual Gordon press Iprovide suitable means for securing the same thereto and for adjustingit in proper position and in Fig. i I have shown a simple andefficientmeans to this end.--- As shown I provide a metallic frame206which is secured to the usual feed board support 1 of the press bymeans of the screw bolts 207. For the purpose of adjusting or levelingthe parts 206 and 1. I provide adjusting screws 208. The attachment isconnected to and supported by the frame 206 by a parallel ruler motionwhich not only permits the attachment to ,be

moved outwardly from its operative position but also is adapted tomaintain the attachment in working position to which it is adjustable.As shown, parallel links 209 are pivotally connected at their lower endsto the frame 206 and at their upper ends to the main frame 4 ofthe'attachment. When the attachment is in proper working position it issecured to the 7 thereof;

rame 206 by means of the screw bolt 210 having the hand wheel 211. Theattachment is properly leveled or adjusted by means of the adjustingscrews 212. l
